Figure F17. A. Reworked zeolite grain in sandstone of Facies IC. The detrital zeolite grain originated in the spherolite cements of Unit II sandstones (see Fig. F21) and thus indicates erosion of older sedimentary rocks (smear slide from Sample 195-1201B-7X-2, 147 cm [49.67 mbsf]). B. Glass shards from a pumice ash layer within Facies IIA. Most shards show abundant pipe or bubble vesicles (smear slide from Sample 195-1201B-8X-6, 7 cm; 58.97 mbsf). Both photomicrographs were taken in plane-polarized light.
